The invention discloses a traffic flow generation method and a related device, and the method comprises the steps: determining a road parameter according to a target test function, determining a target test road corresponding to the road parameter from a road classification library comprising a plurality of test road resources, determining the random parameters of a plurality of random vehicles according to the target test road, and generating a traffic flow according to the random parameters. The random parameters comprise initial positions of the plurality of random vehicles, a traffic flow radius formed by the plurality of random vehicles and a driver model of the plurality of random vehicles, and generating a first traffic flow according to the target test road and the random parameters. Therefore, permutation, combination and screening are not carried out for different elements of the scene any more, testing is carried out according to different testing functions, namely, the road parameters and the target testing road are determined according to the target testing function, and therefore random parameters of multiple random vehicles needed by the target testing function are generated in a targeted mode; therefore, the traffic flow suitable for the target test function is generated in a targeted manner, the occurrence of a large number of unreasonable scenes is avoided, and the test efficiency is improved.

    本申请公开了一种交通流生成方法和相关装置,根据目标测试功能确定道路参数,从包括多种测试道路资源的道路分类库中确定该道路参数对应的目标测试道路,根据目标测试道路确定多辆随机车辆的随机参数,随机参数包括多辆随机车辆的起始位置、多辆随机车辆构成的交通流半径和多辆随机车辆的驾驶员模型,根据目标测试道路和随机参数生成第一交通流。由此,不再针对场景的不同要素进行排列组合和筛选,而是根据不同的测试功能进行测试,即根据目标测试功能确定道路参数和目标测试道路,从而有针对性的生成目标测试功能所需的多辆随机车辆的随机参数,进而有针对性的生成适用于目标测试功能的交通流,避免了大量不合理场景的出现,提高了测试效率。
